Everest 2020 elevation measurement postpones peak date

Original title: Everest 2020 elevation measure postponed

The reporter learned from the Mount Everest 2020 mountaineering team that due to snow on the climbing route, the date of the summit measurement will be later than planned.

Wang Yongfeng, the person in charge of the mountaineering activity of the Mount Everest 2020 elevation survey, introduced that on the 8th, all members of the mountaineering team of the Mount Everest 2020 elevation survey rested in the front camp at an altitude of 6,500 meters. On the morning of the same day, the Tibetan climbing adventureServiceLimitedThe company6 road repairers (i.e. to protect the rope on the mountain, tracking climbers canBorrow(Climbing) guide and 27 peopleSuppliesTransportThe staff departed from the front camp and prepared to traverse the North Col ice wall at an altitude of 7028 meters. When they climbed to an altitude of 6,700 meters, they discovered that the snow on the climbing route was deep and that there was a danger of it melting away. All staff retired to camp.

Wang Yongfeng said that, according to the trial, the summit measurement time will be delayed compared to the original plan.

The survey mountaineering team leader fell to the forward camp at an altitude of 6,500 meters. On day 9, the plan to go to the camp at an altitude of 7028 meters was canceled. All team members will continue to rest in the advanced camp, practice using measuring instruments, and complete climbing skills training. Currently, all players are in good condition. On the 10th, the road repair team will go 7028 meters above sea level to explore the road and determine the risk of snow drifts in the section below the North Hill and determine the next climbing schedule.

New snow and old snow are not integrated, so climbing is not adventurous

Previously, many trainers from the China Mountaineering Association and guides from the Tibet Sacred Mountain Company who participated in the climb told reporters that the “way” to the summit is expected to be repaired from 9-10, which which means that the protective rope will be placed up to Summit of Everest. Once the lanyards are in place, the mountaineering gear measurement will be just around the corner.

But just a day later, the situation on the mountain suddenly changed. In this regard, relevant meteorology and mountaineering experts said: The plan cannot keep up with the changes, which is the normal state of mountaineering activities. Snow conditions on the climbing route, peak weather, and even material safety will affect the timing of the summit. The mountainous climate is changeable and climbing is not risky. The mountaineering team must adjust the plan according to various factors at any time.

Everest 2020 elevation survey mountaineering activity leader and vice president of the China Mountaineering Association Wang Yongfeng said the previous weather forecast showed May 12 to be a suitable window for the summit, but only It lasts a day and requires a very tight climbing schedule. This time, the climbing route from the camp at 6,500 meters above sea level to Bei’ao was blocked, preventing the mountaineering team from catching up with this window.

“A few days ago, there was a lot of snow in the front camp and in Beiao, so the snow on the mountain was very deep. The guide considered that if it was strong, an avalanche could occur,” said Wang Yongfeng.

Several guides from the Holy Mountain Company stationed at Qianjin Camp confirmed Wang Yongfeng’s statement. They said that after several consecutive snowfalls on the mountain, the new and old snow did not mix well and the snow conditions were weak. A guide said that this year affected by the epidemic, foreignBusinessMountaineeringThe teamBoth canceled the climbing plan on the north slope, and the number of people on the mountain became smaller: “No one stepped on it after the snow fell, which is false.”

The temperature is close to minus 30 and the wind speed is up to 20 meters / second.

Reporters from the Xinhua News Agency personally experienced the unpredictable weather of Mount Everest during the interview on March 9 from the hiking camp at an altitude of 5800 meters at an altitude of 6500 meters. The camp was bright in the morning when he left in the morning, but it was already full of wind and snow when he went to camp. Some climbers said, “Except that there is no summer, you can experience” three seasons a day “on Mount Everest.”

“The local weather in the mountain area is changeable, and it is common to make changes to the climbing plan within a day.” Wang Yongfeng said that this year, mountaineering organizers are also referring to mountaineering weather forecasts provided by the Tibet Autonomous Region Meteorology Department and Swiss professional agencies, which can usually be done five or six days in advance . Forecast “Generally speaking, what we value most is the forecast at an altitude of more than 8,000 meters, because it is directly related to the weather at the top,” he said.

The head of the surveying meteorological support service, Shi Lei, deputy director of the Shigatse Meteorological Office, said the meteorological department will provide the mountaineering team with forecasts for different heights and different time periods at base camp and in the mountains. The temperature of 8,000 meters above sea level in recent days is understood to be close to minus 30 degrees Celsius, and the wind speed can reach about 20 meters per second.

Wang Yongfeng introduced that the proper weather window for the summit of Mount Everest is best free from strong winds and blizzards. Among them, the wind has a greater impact on the summit, which will cause the temperature to drop linearly, hinder the ride and easily cause freezing, snow blindness and other dangers.

Climbing can’t worry, just adapt to changes

“Generally speaking, the windows of the summit of Mount Everest in spring usually appear in May. After June, the monsoon season enters and the snow continues to rise on the mountain. It is difficult to climb; although the weather improves in autumn The previous snowfall will make the altitude seven to eight thousand. The snow in the area is more than two meters thick, and in the long winter of Mount Everest, the strong wind on the mountain will prevent climbers from advancing. therefore, most climbers will choose to reach the top in May, “said Wang Yongfeng.

Some professional guides who have been climbing Mount Everest for many years feel that the snowfall on Mount Everest this spring is more than in previous years. Wang Yongfeng said that in the past, snow was rarely found to be blocked from 6,500 meters above sea level to Bei’ao, and that bad weather often affected the peak stage from 8300 meters above sea level. .

In this regard, Shi Lei said that the trends of climate changeLong-termMeteorological data is compared. Currently, there is no research conclusion on this aspect in local meteorology.

It is understood that on the 10th, the Shengshan Company road construction team will go at an altitude of 7028 meters to explore the road to determine the risk of snow drift in the section below Beiao and determine the next schedule. A mountain guide said: “Climbing cannot be rushed. Good weather will definitely come, we just need to adapt to the changes and wait patiently.”
